We have different stages we go through when we sleep, and these cycles usually occur every 90-120 minutes. REM, which is rapid eye movement, is a state where you are in the deepest sleep. REM increases as more sleep cycle happen throughout the night. Dreaming happens when you in the REM state. Whereas non-rem sleep stages is where you are building up to the deep sleep REM stage to dream. During the REM stage, the brain is active and this is why intense dreaming happens. During this stage is also when you build energy for the brain and body for the following day. REM is only about 20-25% of our sleep cycle, but it's the stage where the most is happening and when your heart rate and breathing quickens.
